Frequently Asked Questions
Learn more about static vs dynamic QR codes, print resolutions, and privacy.
Do these QR codes ever expire?
No, never! Commercial generators use "dynamic" redirect links that redirect through their cloud servers and expire unless you pay a monthly fee. FileFryer generates 100% static, raw QR codes where your content is directly encoded into the graphic pattern, meaning they work permanently without expiration.
Is my Wi-Fi password or private note safe?
Yes, completely. The QR matrix calculation happens entirely inside your browser using JavaScript. Not a single character of your Wi-Fi password, URL, or notes is ever sent to a server.
What is QR Code Error Correction (L, M, Q, H)?
Error correction allows QR codes to be scanned even if portions of the code are scratched, smudged, or covered. Level L recovers 7% of damaged data, Level M recovers 15%, Level Q recovers 25%, and Level H recovers up to 30%.
Can I print these QR codes on business cards and posters?
Absolutely. For small prints, our 1024px or 2048px PNG export ensures crisp lines. For commercial printing, flyers, and large billboards, download the Vector SVG format for infinite scaling without pixelation.
Does this QR generator work offline?
Yes! You can disconnect your internet completely and generate unlimited QR codes. Everything runs locally on your device.
Can I customize QR code colors while ensuring readability?
Yes. You can customize both the foreground and background colors. For reliable scanning across all smartphone cameras, always maintain high contrast between a dark foreground and a light background.
